Phase-Shifting Transformers
This Special Application Transformer is designed to handle non-linear, non-sinusoidal loads resulting from their use with a variety of power electronic applications such as diode, thyristor or motor drive configurations from 6, 12, 24, 36, 48, or 60 pulse configurations.
Transformer Specifications
Special design considerations should be used to account for the additional harmonic heating, more severe axial forces, severe overloads and short circuit forces that can be seen as compared with a standard power transformer. Niagara Power Transformer’s superior engineering expertise paired with its unmatched years of manufacturing experience and high-grade materials allow us to provide the best in-class Special Applications Transformers.
